  slenderer, 
  the 
  chelae 
  less 
  swollen 
  toward 
  the 
  base, 
  and 
  armed 
  above 
  

   with 
  stronger 
  spinules, 
  which 
  are 
  Avhite, 
  and 
  contrast 
  strongly 
  with 
  

   the 
  red 
  ground-colour 
  of 
  the 
  palms. 
  It 
  is 
  possible, 
  but 
  I 
  do 
  not 
  

   think 
  it 
  probable, 
  that 
  this 
  species 
  is 
  a 
  variety 
  of 
  C. 
  vulgaris 
  ; 
  the 
  

   figure 
  of 
  Quoy 
  and 
  Gaimard 
  was 
  originally 
  cited 
  by 
  M. 
  -Edwards 
  as 
  

   synonymous 
  with 
  that 
  species 
  ; 
  nor 
  can 
  I 
  be 
  certain 
  that 
  the 
  distinc- 
  

   tions 
  mentioned 
  exist 
  in 
  M.-Edwards's 
  C. 
  vulgaris, 
  not 
  having 
  seen 
  

   the 
  types. 
  

  

  Another 
  very 
  small 
  specimen 
  of 
  this 
  genus 
  is 
  in 
  the 
  collection 
  from 
  

   Port 
  Molle 
  (No. 
  118), 
  which 
  can 
  scarcely 
  be 
  referred 
  with 
  certainty 
  

   to 
  any 
  species. 
  

  

  9. 
  Eupagurus 
  compressipes. 
  (Plate 
  XXVIII. 
  fig. 
  B.) 
  

  

  The 
  carapace 
  is 
  nearly 
  smooth, 
  moderately 
  dilated 
  at 
  the 
  branchial 
  

   regions, 
  with 
  the 
  cervical 
  suture 
  very 
  distinctly 
  defined 
  ; 
  the 
  frontal 
  

   margin 
  between 
  the 
  eyes 
  is 
  very 
  little 
  prominent, 
  and 
  there 
  is 
  no 
  

   median 
  rostriform 
  projection, 
  and 
  but 
  two 
  small 
  triangular 
  teeth 
  

   on 
  the 
  frontal 
  margin, 
  situate 
  one 
  on 
  the 
  outer 
  side 
  of 
  each 
  eye- 
  

   peduncle. 
  The 
  eye-peduncles 
  are 
  shorter 
  than 
  the 
  carapace 
  is 
  wide 
  

   in 
  front, 
  robust, 
  and 
  have 
  the 
  cornese 
  somewhat 
  dilated 
  ; 
  their 
  

   basal 
  scales 
  are 
  dilated 
  at 
  base, 
  narrow, 
  subacute, 
  and 
  entire 
  at 
  

   apex, 
  with 
  the 
  margins 
  ciliated 
  but 
  not 
  denticulated. 
  Antennulary 
  

   flagella 
  very 
  short. 
  The 
  bases 
  of 
  the 
  antennae 
  bear 
  a 
  short 
  spine 
  on 
  

   their 
  outer 
  margins, 
  which 
  docs 
  not 
  reach 
  halfway 
  to 
  the 
  apex 
  of 
  the 
  

   eye-peduncles 
  ; 
  articulated 
  with 
  the 
  dilated 
  base 
  of 
  this 
  is 
  a 
  longer 
  

   spine, 
  which 
  is 
  serrated 
  on 
  its 
  inner 
  margin, 
  and 
  prolonged 
  above 
  

   the 
  bases 
  of 
  the 
  antennae 
  nearly 
  to 
  the 
  end 
  of 
  the 
  eye-peduncles, 
  on 
  

   the 
  inner 
  side 
  and 
  at 
  the 
  base 
  of 
  which 
  is 
  a 
  small 
  spiuule. 
  The 
  

   joints 
  of 
  the 
  flagella 
  of 
  the 
  antennae 
  are 
  setose. 
  The 
  outer 
  maxilLi- 
  

   pedes 
  are 
  remote 
  from 
  one 
  another 
  at 
  their 
  bases, 
  and 
  the 
  inner 
  

   margins 
  of 
  the 
  ischium-joiuts 
  are 
  denticulated. 
  The 
  legs 
  are 
  pubes- 
  

   cent 
  ; 
  the 
  right 
  chelipede 
  is 
  more 
  robust, 
  but 
  little 
  longer 
  than 
  the 
  

   left 
  ; 
  the 
  outer 
  margins 
  of 
  the 
  merus-joints 
  in 
  both 
  chelipedes 
  are 
  

   spinulose 
  toward 
  the 
  distal 
  extremities, 
  the 
  carpus 
  spinuloso 
  on 
  its 
  

   inner 
  margin 
  and 
  on 
  its 
  upper 
  surface 
  ; 
  the 
  hand 
  in 
  the 
  larger 
  

   chelipede 
  is 
  narrow-ovate, 
  and 
  very 
  obscurely 
  spinulose 
  on 
  the 
  

   margins 
  and 
  in 
  the 
  middle 
  of 
  its 
  outer 
  surface, 
  the 
  spinules 
  or 
  

   granules 
  nearly 
  concealed 
  by 
  the 
  pubescence 
  ; 
  the 
  fingers 
  are 
  rather 
  

   shorter 
  than 
  the 
  palm, 
  denticulated 
  on 
  their 
  inner 
  margins, 
  acute 
  at 
  

   their 
  apices, 
  and 
  have 
  between 
  them 
  no 
  hiatus 
  when 
  closed 
  ; 
  the 
  

   smaller 
  (left) 
  hand 
  is 
  similar, 
  but 
  slenderer. 
  The 
  first 
  and 
  second 
  

   ambulatory 
  legs 
  have 
  the 
  joints, 
  except 
  the 
  daetyli, 
  somewhat 
  dilated 
  

   and 
  compressed, 
  the 
  merus-joints 
  with 
  a 
  series 
  of 
  spinules 
  on 
  their 
  

   anterior 
  margins 
  ; 
  the 
  daetyli 
  longer 
  than 
  the 
  preceding 
  joints, 
  

   slender, 
  somewhat 
  compressed 
  and 
  curved, 
  but 
  not 
  contorted. 
  The 
  

   acute 
  infero-distal 
  angle 
  of 
  the 
  penultimate 
  joint 
  of 
  the 
  fourth 
  legs 
  is 
  

   produced 
  halfway 
  along 
  the 
  inferior 
  margin 
  of 
  the 
  dactylus. 
  The 
  

   fifth 
  legs 
  are 
  subchelate, 
  and 
  the 
  chelaj 
  densely 
  hairy. 
  The 
  male 
  

   postabdomen 
  (as 
  well 
  as 
  the 
  female) 
  bears 
  several 
  pairs 
  of 
  filiform
